Incorporating Clean Shipping International

A mobile ballast water treatment system called Ballast Responder has been demonstrated onboard the Great Lakes-operating bulk carrier Tim S. Dool.

Ballast Responder was developed by Glosten in cooperation with Global Diving & Salvage, the US Geological Survey and the US National Park Service. The small mobile system is designed to be easily transported to any location to treat vessels that have unmanaged or untreated ballast water in port, grounding, or other emergency situations. The Great Lakes demonstration was supported by the National Park Service and the Chamber of Marine Commerce and was conducted on an Algoma-operated vessel.

Glosten Principal and ballast water treatment expert Kevin Reynolds said: “Equipment was operational within eight hours of arrival and the first set of tanks were fully treated, neutralised, and ready to discharge only 20 hours later.”

The first test treated three ballast water tanks holding 2400m3 of ballast water.  This was treated and neutralised in the tanks during transit through the Welland Canal. The treated water was then discharged in Lake Erie.  A second test was also performed in-voyage, this time treating another 2400m3 of ballast water taken up outside of the Detroit River and discharged in Lake Superior.

“This provided the opportunity to evaluate the performance and practicality of Ballast Responder on a working Great Lakes bulk carrier to treat challenging fresh water and challenging tank configurations,” said Reynolds.

“Having the ability to perform contingency treatment of ballast water on ships that are working the Great Lakes is very important to us,” added Phyllis Green, Superintendent of Isle Royale National Park in Lake Superior.

Moss Landing Marine Laboratories was onboard vessel during the voyage to carry out an independent assessments of system biological efficacy.
